Testectomy

Surgical Procedure

Testectomy is the excision of one or more testes, also known as orchiectomy. This allows for analysis of spermatogenesis, generating greater understanding of sex hormones in development and metabolism. Studies with NHPs have analyzed expression of LIN28, an RNA-binding pluripotent stem cell factor (verified by western blotting and quantitative RT–PCR) and has demonstrated striking differences in expression profile among species.

About our nonclinical animal research models: We provide the utmost care for our research animals and actively pursue advances in animal welfare. As well as ensuring the highest scientific, ethical and regulatory standards, selection of appropriate animal research models for development research is critical to developing safe and effective treatments, devices and products that protect and save lives. Just as we have ethical committee oversight for human trials, we have ethical committees overseeing all aspects of our global animal care and use programs. All of our core, nonclinical facilities are accredited by AAALAC. Learn more about our commitment to replacing, reusing and refining nonclinical research models.
